Article summary

The article introduces a free online textbook on compilers and language design, written by Prof. Douglas Thain, which provides a one-semester introduction to compiler construction. The book enables readers to build a simple compiler that accepts a C-like language and translates it into working X86 or ARM assembly language. The textbook is suitable for undergraduate students with experience in programming in C and courses in data structures and computer architecture. The author also provides additional resources, including a GitHub repository with code examples and a mailing list for updates.

Main themes

  • Compiler construction
  • Language design
  • Programming education
  • Textbook review
  • Compiler resources
  • Programming languages

What commenters say

  • The book provides a valuable introduction to compiler construction, but some commenters feel it lacks depth in language design topics.
  • Building a compiler from scratch is a challenging and rewarding project that offers insight into many aspects of computer science.
  • Some commenters believe that the book's focus on C-like languages limits its usefulness, while others appreciate its practical approach.
  • The use of AI-generated code is seen as a concern by some, who feel it can lead to low-quality work and a lack of understanding of underlying principles.
  • Others argue that AI can be a useful tool, but it should not replace human thought and effort in programming and compiler construction.
  • The importance of understanding type systems and programming language theory is emphasized by some commenters, who recommend additional resources such as 'Types and Programming Languages' and 'Essentials of Programming Languages'.
  • The process of language design is seen as complex and nuanced, requiring consideration of human language evolution, formal and informal constructions, and the purposes of language.
  • Some commenters appreciate the book's practical approach, while others prefer more theoretical or advanced treatments of compiler topics, such as those found in 'The Dragon Book' or 'The Tiger Book'.
